Be itknown that I, CHARLES EDMUND,

KELLS, a citizen of the United'States, residing in New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Water-Distilling Apparatus, of which the following is a specification;

This invention relates to apparatus for distilling water, particularly for use of: physicians, surgeons and dentists who require watching in order that the water supply.

shall not fail because otherwise the glass flask, when such is employed, will be cracked, burned or broken by the heat'of the burner unless the fuel supply is shut off, In my U. Sl Patent No. 1,366,465 of Jan. 1921, and in my applications for patent No. 398,859, filedv July 26,1920, and No.

403,467, filed Aug. 14, 1920,11 have shown.

apparatus so constructed'as to automatically shut off. the fuel. supply when the water supply fails, or when the receiver for the distilled water is filled to the desired extent. Said prior patent and the two applications mentioned show different modifications of apparatus which maybe used for this'purpose. According tomy present invention Ihave devised a new form ofapparatus embodying certain improvements.

The improved apparatus is automatic in the control of the supply of the heating. medium'which is admitted to the burner for carrying on the operation as long as the water supply continues, but the construction 7, is such that should the water supply fail or become insufficient. the fuel supply will be at once automatically cut off so that breakage of any part of the apparatus from overheating is prevented. This is accomplished in the preferred way, by causing water from the water supplyito pass to a flask or still and also to a vessel mounted on one end of a lever, the other end of which Galriesa Application 'filed April 9,

Saidvessel is meiaed with overflow pipe whereby the level in said vessel is normally kept constant, but the vessel'is also provided with an 1 exit by means of which the vessel may be drained and thus the weight of the vessel and its contents re ducedu This causes the lever to be turned and'said lever is'connectedlwith a valve in 1 the fuel supply pipe which is automatically closed when the. water supply fails or is I.

These'parts A, B, C, 'Diai d I E- are preferably made of glass, for I the reasons before stated, g 1 I Water enters he coil ,through a pipe 0' which may be connected to a tank or service pipe. After passing throughthecoil the water leaves the condenser at e and: passes into a tanker vessel F the bottom of whichis connected by a'pipejf with the flask or.

overbalances the weight N. Anoutlet h is when the supply of water from the pipe G ceases the water runs out ofthe vessel-l the wei ht N overbalances saidvessel.

The ask or stillAis heated. by a burner O, supplied by a pipe P. pipe P is" normally held open by an arm R which engages a lu 70 on the lever Klbut the arm is weighte as indicated at -1 so thatwhen the arm is disengaged from the lug 7c the arm will turnand. the valve'will be closed and thus the supply of fuel will 10c formed in the lower part of the pipe 71, and v and A valveo in the be cut off and danger of overheating the apparatus prevented,

In starting the operation the water supply is turned on and water is conveyed by the pipe 6 through the condenser'to the vessel F which it fills and from this vessel the flask or still A is filled to the same level as the water in the vessel F. The supplyof water to the vessel F is more than suiiieient to supply thestill and-it overflows through the pipe G into the balancing vessel H which it fills to the top of the overflow pipe it. The supply is suflicient to normally provide an overflow through ;the pipe 7t and through the outlet opening it. hen thus started the Water supply and the fuel supply are suflicient to continue the distilling operation. It will be observedfthat the ves- V sel H holds the valve 0 open when said vessel is filled withwater, but should the supf ply of'water to the vessel fail or be un- .duly "reduced, the tank will be drained ceives the distilledwater. This construction through the exit opening it which of course decreases the weightand therefore the weight N overbalances, the vessel HQand the lever K .is turned in such imanner as to release the Weighted arm R and the valve 0 in the fuel supply pipe is automatieallyelosed. The movementsof the lever arm'inay be con: trolled bye op e The apparatus herein shown and def 31p? '14:, 1920 in that a weight is supported on the lever K insteadof'th'e vessel which'rehas advantages in some cases. In the prion application just referred to the amount of distilled Water received in the' vessel is limited; When 'saidYvessel, whiclrmay be. relatively small, is full the" operation is stopped, but in the apparatus shown in the accompanying drawings and hereinhefore explained, areceiving vessel D for distilled Water of unlimited capacity may be employed and the operation may continue indefinitely or vuntil it 'is designedly stopped or the supply of waterisunexpectedly arrested.
